OIL-BURNING HEATING APPARATUS.

Specification of Letters Patent.

Application filed. March 30, 1909. -Sria1 No. 486,681.

To all whom it may concern:

Be it known that I, THEODORE LEMBKE, a citizen of the United States,residing at Buffalo, in the county of Erie and State of New York, haveinvented a certain new and useful Improvement in Oil-Burning HeatingApparatus, of which the following is a specification.

This invention relates to an improved oil burning heating apparatus andthe object of the invention is to produce an apparatus for heatingbuildings In which oil serves as the heating agent.

Another object of the invention is to construct the burner in suchmanner that the combustion chamber can be entirely inolosed as toexclude all air except that which enters through the burner and thusobtain a more even combustion and a greater degree of heat.

Another object is to so construct and arrange the heating chamber thatthe heat is utilized to the fullest possible degree in heatin the air asit passes therethrough and thus e ect a decided saving in cost ofoperation.

The invention also relates to certain details of construction, all ofwhich will be fully and clearly hereinafter described and claimed,reference being had to the accompanying drawings, in which,-

Figure 1 represents a central vertical longitudinal section through thefurnace of the improved apparatus showin a side elevation of theremainder thereo Fig. 2 is a horizontal section through the furnace online a a, Fig. 1. Fig. 3 is an enlarged detached sectional view of oneof the burners.

In referring to the accompanying drawings for the details ofconstruction, ike nu merals designate like parts.

The furnace of the improved apparatus consists of a combustion chamber1, a heating chamber 2, .-an outlet chamber 3 communicating with thestack 24, and a supplementary heating chamber 4 extending around theends and outer side of the outlet chamber and forming an auxiliarypassage for air.

The combustion chamber 1 is inclosed by side and end walls 5, 6, 7 and8, and top and bottom brick walls 9 and 10, so that it is whollyinclosed and walled in with fire.- proof material.

The rear wall 8 of the combustion chamher 1 forms the separatingpartition be panded in openings in the plates to securely fasten themtherein. Transverse openings 14 armtormed 1n the vertical wall 8 and register with the fiues 13 so as to provide uninterrupted passage from thecombustion chamber'l to the outlet chamber 3.

A pipe 15 leads from the outside ofgthe building through the side wallof the -fiirnace and communicates with the heating chamber 2 forminganinlet passage for unheated air. Another pipe 16 is connected at itsend to the opposite wall of the furnace and provides a passa e forconducting the heated air from the urnace to the various fines or pipesleading to the different portions of the building.

A fan 17 is located in this outlet pipe 16 and serves to draw a currentof pure fresh air into the heating chamber 2 through the inlet pipe 15and then after it is thoroughly heated into and through the outlet pipe16 to the pipes or fiues for conducting heated air.

The rear supplementary heating chamber 4 is separated from the outletchamber 3 by a vertical metal plate 18 and a similar plate 19 forms therear wall of said chamber.

The heating chamber 2 and the outlet and supplementary chambers 3 and 4are closed at the sides, top and bottom by metal plates 20, 21, 22 and23, the top plate having an opening out therein directlyabove the'outletchamber for the escape of gases into the stack 24.

The supplementary heating chamber 4 is of a narrow elongated formextending longitudinally of the furnace and has its ends extending atsubstantially right angles to extend in heating proximity to the ends ofthe outlet chamber and also to provide passages,

25 and26/ which communicate respectively with the inlet and outlet pipes15 and 16, see Fig. 2.

The burner consists of a pipe 27 leading through the side wall 6 intothe combustion chamber 1 and a pipe 28 of smaller diameter which entersthe pipe 27 outside the combus-.

. tion chamber and extends but a short disoil through the pipes 31 and28 into the pipe 27 which constitutes in reality a blast pipe t-ancewithin said pipe.

The pipe 27 is connected by a pipe 29 to a tank 30 adapted to containcompressed air, and the pipe 28 is connected by a pipe 31 to a tank 32which serves as a reservoir for the,

oil.

An air compressor 33 is .connected to the compressed air tank 30 by apipe 34 and also to the oil reservoir 32 by a pipe 36 to supply airthereto. By forcing air 1nto the reservoir the oil is fed into the pipe27 within the combustion chamber. i

The pipes 29, 31, 34 and 36 are-provided with valves 37, 38, 39 and 40by means of which they may be closed against the passage of air or oil.

The air compressor is driven by a belt 41 .which runs on a pulley 42 onthe comfrom whence it is ejected. The compressed air an the oil areunited as they leave the nozzle and burn with an intense heat in thecombustion chamber.. From the combustion chamber the heat passes throughthe flues 13 which become heated to a high temperature, and into theoutlet chamber from whence the remaining gases pass out through thestack. As the a r 1s drawn into the heating chamber by the fan 17 ifithepassage 16 it comes into contact with the heated flues and imme-.diately becomes heatedand then passes on\ through the passage 16 intothe flues leading to the diflerent portions of the building. The air inthe supplementary heating chamber 4 which is heated by contact with themetal plate formin the rear wall of the outlet chamber, is rawn into theheating chamber throu h the connecting passage by the suction of t efan.

By referring to Figs. 1' and 2 it will be noted'that the flues arestaggered so that no air currents can pass directly throu h the heatingchamber but must pass aroun them in a' sinuous course. In this way theair is quickly and'thoroughly heated to such a tem erature thatall-germs'and foreign matter is destroyed.

The currents of air in passing through the heating chamber move in adirection approximately transverse to or across the flues so that theheat units thrown off by the gases of combustion passing through theflues are fully and efliciently' utilized. 1

When starting the furnace a number of bricks are removed from the wallof the mace, a bottom wall, a top wall havin combustion chamber exceptthrough the blast pipe.

One or more burners can be used, the number varying with the size andcapacity of the apparatus.

In this construction the four chambers of which the furnace consists arearranged side by side in a horizontal row as shown in Figs. 2. I I

One of the principal advantages of this improvement is that the productsof combustion are entirely isolated from the air so that they cannotcontaminate or become mixed with the air as it is passing through thefurnace.

Another advantage resides in the thorough and eflicient manner in whichthe heat is utilized, air being drawn through the heating chamberbet-ween the flues and also around the outer side of the outlet chamberwhich practically forms a continuation of the heating chamber as one endof the flues extends through the wall between the heating chamber andthe outlet chamber and conducts the heated products of combustionto'said outlet chamber.

A furnace having side walls, end walls provided respectivelywith an inlet and outlet for the passage of air through the furnace, abottom wall, a top wall havin an outlet opening for-thev roducts of comustion, vertical longitudinal and transverse -partitions extendinbetween the-bottom wall and the top wa and dividing the interior of thefurnace into a plurality of chambers, there being a comparatively largechamber centrally located and forming a heating chamber, a chamber onone side of the heating chamber forming a combustion chamber and achamber on'the opposite side of the heatin chamber forming an outletchamber and ein in communication with the outlet opening in the top.wall and a lurality, of flues havin their ends exten ing to and throughthe ion 'tudinal partitions formin the side walls 0 the heatin chamberan afiording communication etween the combustion chamber and the outletchamber and a chamber'extending on the exterior of the outlet chamberforming a supplemental heatin chamber, the said outlet chamber exten ingsubstantially across one side/and from top to bottom of said furnace andthe outer wall of said outlet chamber forming the inner wall of saidsupplementary heating chamber.
